One Sock Ball per Cup
Your toddler drops rolled-up adult socks into the cups of a muffin tin, one per cup, hearing 'one', 'another' and 'full' as the tin fills.

You need
- a 6- or 12-cup muffin tin
- 6 adult socks rolled into tight balls
Steps
- Roll adult socks into tight balls and set the muffin tin on the floor.
- Drop one sock ball into a cup and say 'One in.'
- Hand your child a sock ball and wait; let them choose any cup.
- If they aim for a cup that already has a sock, say 'That one's full. Another cup?' and point once to an empty one.
- When every cup is full, say 'All full!' and tip them out together.
Safety first
- Roll socks tightly so each ball stays bigger than a toilet-paper-tube opening; skip baby socks, which can be stuffed into the mouth.
- Use a muffin tin with smooth, rust-free edges and keep it on the floor so it cannot fall on toes.
No level picked yet. The 0–4 scale is a learning log, not a test.
Not yet: show it once, then let them explore
Watch for the first sign: places a sock ball in an empty cup rather than a full one.
Not yet is information, not a verdict. Do it once yourself while they watch, pause, and offer it again in a few days.
Simplify one step
Next time: cover all but two or three cups with a tea towel so there are only a few spaces to fill.
Give the least help that works: wait first, then point or show, and guide hands only briefly.
Repeat the same version and fade your help
As you step back, watch for: fills several cups in a row without help.
Pause a few seconds longer before you model, and swap showing it for a point or a gesture.
Offer it once more, then add one change
When it is easy again: uncover more cups so there are six spaces to fill.
Change only that one thing and keep everything else the same.
Ready for one step up
Uncover more cups so there are six spaces to fill. Or carry it somewhere new: set one spoon beside each plate at dinner and say 'one for each'.
Starting it on their own or using it in a new place is the strongest sign. Still change one thing at a time.
Stop and rest this one
In 2-3 days, come back with the simpler version: cover all but two or three cups with a tea towel so there are only a few spaces to fill.
End with something calming together. One hard moment never means a delay.
Stop on a good note
Keep this version and keep it short next time: 5 minutes is plenty.
They can do it, but it was not fun today. Add difficulty only once it feels easy and enjoyable again.

Why it works
AAP's toy report notes that simple containers and household objects support early problem-solving and number ideas when an adult plays along. One object in each space is a playful first taste of one-to-one matching, not a counting test.
Evidence rating: Good: published guidance supports the approach. Cited: AAP clinical report: Selecting Appropriate Toys for Young Children in the Digital Era (Pediatrics, 2019).
